Well some problems with making a standart film into an IMAX release are:
Imax prints, by cellulloid material alone, cost 8 times what a 35mm print costs. That's not counting that 35mm prints are done in large quatities, and not all labs are equiped to handle 70mm wide film, so they cost even more much more to proccess than 8x, making IMAX prints true "limited" editions, so it may not be cost effective to do an IMAX release
As Luke mentioned in this post some 35mm films blown up straight might not take kindly being enlarged up to 11x times their original designed size (as would be the case, for example, of The Little Mermaid, which most of it wasn't done in the CAPS format)
IMAX prints have an image area roughly 50mm x 70mm, while Litle Mermaid's negative was (@1.75) 12mm x 21mm (or if you included the whole extra image area of the camera aperture around it till it reached the rightmost sprocket and the left sound area (and present it 1.66), 13mm x 22mm)
so an IMAX film, at the sizes/seating distances presented wouldnt reach its potential (woudn't look totally sharp) till it had a 4000 x 6000 pixel resolution source or maybe even more!
That may be one of the reasons IMAX releases of the CAPS features get redrawn/re-rendered: to increase the detail cus in the IMAX screen they really need it (For curent home video formats, which is around 400-500 pixels, that new detail is mainly redundant

)
Having said that, and with today's (or tomorrow's

) technology, it may be posible to scan the ORIGINAL negatives (which have the most detail and the least grain) and digitally apply NON-DESTRUCTIVE grain removal (if it's the bad kind, your detail gets wiped out with the grain) and advanced upsampling and judicious sharpening and create a QUASI-4000 x 6000 image and laser burn that into an IMAX print which would give the finest presentation possible of the movie so it wouldn't look worse that the 35mm version but might look the best ever and probably with more edge sharpness and steadier image. (Cus the projectors vibrations and the lens aberrations of the projector's AND blow-up lenses are reduced or eliminated, and you're making a laser positive, in a sense, of the fully extracted original negative data)
But hey add up that to the cost and you see why we no get that much IMAXES

That movie, and a small amount of other Disney titles, practically deserves to be seen on the largest screen possible.
YES!
